The proposed Battery addition project is a 6.7 MW hybrid development located in Franklin County, Massachusetts. Interconnecting in the ISO-NE queue as queue ID 1149 on August 6, 2021, the project consists of a 6.7 MW hydro component and a battery component. Its proposed commercial operation date is August 17, 2025.
The project's interconnection agreement status is listed as "In Progress (unknown study)" within the ISO-NE queue. The point of interconnection is National Grid's PTF (E-5B, F-6 West PTF transmission lines). The developer is not specified in the queue data.
